A lock plug spinner is a pin-tumbler lockpicking tool used to rotate a plug that has been picked in the wrong direction. This is a common problem for locksmiths and physical penetration testers.
Plug spinners work by rotating the plug so rapidly that the spring-biased driver pins do not have enough time to fall back down into the plug's pin chambers.
